Cleu is an iOS app designed for smart contact management. Our app offers the following key features:
Detects contacts with the same name, phone, or email address using AI-powered algorithms
Merges duplicate contacts with manual review
Securely stores deleted contacts and offers restoration capability
Automatic cloud backup for premium users
Full localization in 13 different languages
Personalized reminders and updates
Dark/Light mode support and accessibility features
Cleu's core design principle is that you have full control over your personal data. All operations with your contacts (finding duplicates, merging, deleting, backing up) occur directly on your device.
Your contact list or any data within your contacts is never uploaded to our servers, read by us, or shared with third parties.
For the app to function, access to your "Contacts" is requested via the iOS standard permission mechanism.
This permission is used for the following features:
We collect the following anonymous data to improve the app experience:
Is completely anonymous
Contains no personally identifiable information
Is not associated with contact content
Is used solely for app improvement purposes
Access to your contact data is used solely to provide the services offered by the app, such as cleaning, merging, deleting, and restoring.
The anonymous transaction information we collect helps us understand the most used features and make the app more useful.
Cleu uses two different notification systems:
All your contact data and data in the Secure Vault (if iCloud backup is not active) are stored only on your device. When you delete the app, this data is also permanently deleted.
The local .vcf backup files you create are stored in the app's protected area, and only you can access, share, or delete these files.
You can revoke Cleu app's access to your contacts at any time via iOS Settings > Privacy & Security > Contacts. When permission is revoked, the app will not be able to perform its functions.
You can permanently delete contacts within the Secure Vault or restore them to your contact list.
As a Premium user, you can turn the iCloud backup feature on and off anytime from the app settings.
Our application does not knowingly collect personal information from children under the age of 13 (or the equivalent minimum age in the relevant jurisdiction).
